Abstract

To identify relevant remotely derived environmental indicators specific to biodiversity within the Canadian boreal forest, the AA. assessed indicators of the physical environment such as seasonal snow cover, topography and vegetation production. Using cluster analysis, the AA. also assessed the applicability of these indicators for broad ecosystem classification of the Canadian boreal forest and the subsequent attribution of these stratified regions (i.e. clusters). The results reveal that the indicators used in the cluster creation provided unique information and explained much of the variance in tree (92.6%), bird (84.07%), butterfly (61.4%) and mammal (22.6%) species richness. Spring snow cover explained the most variance in species richness. The most important indicators for discriminating between the different cluster groups were seasonal greenness, a multipart measure of climate, topography and land use, and wetland cover
